REVERSING FRICTIONAL DRIVING iviEcisrAivIsM.

Application filed May 24, 1911. Serial No. 629,175.

Specification of Letters Patent.

Patented Jan. 9,1912.

To all whom it may concern:

Be it known that I, FREDERICK W. DAEU- BLE, a citizen of the UnitedStates, residing at Buechel, county of Jefferson, State of Kentucky,have invented certain new and useful Improvements in ReversingFrictional Driving Mechanism, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements inreversing frictional driving mechanism adapted to be used in connectionwith hoisting apparatus andv especially in connection with hand andpower elevators, the object being to provide a driving mechanism inwhich the movement is transmitted from the driving shaft to the drivenshaft through the medium of a flexible friction disk.

Another object of the invention is to provide novel means for mountingthe frictional disk in order to allow the frictional engaging surface ofthe same to be forced into engagement with either of the driving disksso as to drive the hoisting mechanism in either direction.

A still further object of the invention is to provide a rock framehaving idle rollers opposite the driving disks whereby said disks can beforced into engagementwith either of the driving members for rockingsaid frame in order to reverse the rotation of the disk.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof defined by theappended claims.

In the drawingsFigure 1 is aside elevation of my improved reversingfrictional driving mechanism, partly broken away, in order to show theconnection and manner of mounting the hoisting drums; Fig. 2 is a topplan view of the same partly broken away; Fig. 3 is a verticaltransverse section; Fig. 4 is a section taken on line 4-4 of Fig. 1; andFig. 5 is a section taken on line 55 of Fig. 1.

Like numerals of reference refer to like parts in the several figures ofthe drawings.

In the drawings, 1 indicates a pair of supporting beams which may be ofany desired configuration and arranged in any suitable manner, on whichis mounted a frame 2 having a pair of spaced annularly grooved windingdrums 3 and 4 fixed on suitable shafts 5 and 6 over which is wrapped ahoisting cable 7 to one end of which is adapted to be connected a weightand to the other end an elevator car, not shown.

The shaft 5 carries a gear 8 meshing with .a p1n1on 9 keyed on a shaft10 mounted 1 within the frame which is provided with a beveled gear 11for driving the same which meshes with a beveled pinion 12 mounted upona vertical shaft 13 fixed in the frame,

as clearly shown. It will be seen that when the pinion 12 is rotated,the winding drum 3 will be driven through the medium of the gears inorder to wind or unwind the cable to raise or lower the car.

The pinion 12 is provided with an enlarged disk portion 14 on which isfixed a flexible frictional disk 15 formed of any suitable materialwhich will yield for the purpose later described.

Extending upwardly from the frame 2 in vertical alinement with the shaft10 and in transverse alinement with the shaft 13 are bearings 16 inwhich are mounted trunnions 17 of a rock frame 18 which is provided withlongitudinal shafts 19 and 20 at its ends on which are loosely mountedidle disks 21 and 22 adapted to engage the under surface of the flexibledriven disk 15 when the frame is rocked.

Arranged on the beams 1 are standards 23 and 24 having bearings 25 and26 at their upper ends in which is journaled a driving shaft 27 having apulley 28 at one 'end over which a belt from the motor is adapted topass for driving the shaft, it, of course, being understood that anyother driving gear may be employed as desired. Fixed on the drivingshaft 27 are frictional driving disks 29 and 30, the disks being soarranged in respect to the flexible disk 15, that when said disk 15 isforced into engagement with the disks 29 and 30, they will engage theflexible disk adjacent its edge at each side of its center in order to'allow the disk15 to be driven in either direction by forcing the diskinto engagement with the driving disks.

The shafts 19 and 20 extend outwardly beyond the frame 18 and aremounted in suitable guide ways 31 formed in the standards 23 and 24, theshaft 20 extending through a cam shaped slot 32 formed in a slidablymounted shifting member 33, said member being preferably mounted inguide ways 34, as clearly shown, and can be operated by any suitablemechanism. Fixed on the shaft 20 within the slot 32 is an antifrictionroller 35 adapted to be engaged b the frictional spring members 36 and 3when said shifting member is moved in order to hold the same in positionwithin the slot. It will be seen that when the antifriction roller 35 isin the position shown in Fig. 4, the flexible disk 15 will be held aslight distance away from the driving disks 29 and 30 and by shiftingthe member 33, the frame 18 will be rocked upon its bearings so as toforce either the idle roller 21 or the idle roller 22 into engagementwith the under side of the flexible disk 15 which will yield so as to beforced into frictional contact with one of the driving disks, wherebysaid disk will be driven, which, in turn, through the gears will drivethe drums. When the flexible disk 15 is forced into engagement with thedriving disk 29, it will be driven in one direction and when forced intoengagement with the driving disk 30, it will be driven in a reversedirection, whereby the driving mechanism may be easily and quicklyshlfted.

' While I have not shown a brake, it is, of course, understood that anysuitable form of brake may be employed as desired.

From the foregoing description, it will be seen that I have provided areversing frictional driving mechanism which is ex ceedingly simple andcheap in construction and one which can be readily applied to a hoistingapparatus of a hand or power elevator whereby the movement of thewinding drums can be reversed smoothly so as to avoid any sudden jerkand at the same time a positive drive is formed. It will also be seenthat I have provided novel means for rocking the frame in order to forcethe flexible disk into engagement with the frictional driving disks,tension means being provided for holding the rock frame in its adjustedposition. i c

Having described my invention and set forth its merits, what I claim anddesire to secure by Letters Patent is.
